HOWARD M. DUDLEY, OF PHILADELPHIA, PENNSYLVANIA.

DYEING-MACHINE.

Application filed April 6, 1917.

To all whom it may concern Be it known that I. Howann M. DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inrent-ed certain new and useful Improvements in Dyeing-Machines, of which the following is a specification.

My invention relates to a dyeing machine and refers particularly to a machine adapted for the dyeing of textile fibers compressed within a dyeing chamber, the dyeing being accomplished by the forced passage of the. dye liquor through the fiber mass.

Among the objects of my invention is a dyeing machine particularly suitable for the dyeing of warps in the ball. whereby the condition of the fiber may be accurately and readily judged at any stage of the treatment without opening the dyeing chamber and whereby even results may be obtained without clisturl; ing the fiber to be dyed.

Another object of my invention is a dyeing machine in which the dyed goods may be after-treated with water, steam, air or other materials or substances without handlin the dyed goods. and whereby a series of batches of fiber may be treated simultaneously.

Other objects of my invention will be evident uppn a consideration of my specification and claims.

I have found that the even or uneven dye ing results obtained in a machine of this gem-i-ral character depend largely upon the particular shape of the openings through which the dye liquor enters the fiber mass, and that unevenness can be prevented by the use of openings of a particular shape, the conforlnatitm of which enables the liquor to spread itself through the fiber mass without the formation of channels of flow.

I have further found that this desirable result may be enhanced by inclosing the fiber in a series of containers and passing the treating liquid through these containers and the fiber contained therein, first in one direction and then in the reverse direction.

In the use of many dyestuffs it is necessary. after dyeing to treat the dyed goods with water for washing purposes, or with solutions of chemicals such as metallic salts or oxidizing products for the purpose of Specification of Letters Patent.

after-treatment, or with oxygen or air for oxidizing or drying purposes. In the following of these after-treatments it is essential that every portion of the dyed goods be thoroughly and uniformly treated and that the operationloe performed as readily and quickly as possible. All of these results are obtainable by the use of the device of my invention, in which the goods are placed in the dyeing chamber and then rapidly, easily and completely dyed and aftertrea-ted Without further handling of the goods and without the formation of channels by the liquids employed. The device therefore insures even and uniform results with a minimum of time, labor and expense.

One form of my device is shown in the accompanying drawings in which similar parts are designated by similar numerals.

In the form of my device as illustrated in the accompanying drawings, the truck '20 is mounted upon the wheels 21, 21. which are capable of movement upon the tracks 22, Pivotally mounted upon the truck 20 is a receptacle 23, fixedly attached to portion of the pin on ill which is revoluble within the 'tranie lixedly attached to the pinion it is a toothed. segmental wheel 26, meshing with the teeth of the worm 27. The worm 27 is re oluble within the supports 28, mounted upon the trucl: E20 and is capable of revolution by revolving the wheel 2) fixedly attached to the shaft 30 of the worm The turning oi the wheel theretorc revolves the lQt tacle through the me dium ot the worm 27 and the toothed wheel The receptacle comprised of the MO. shell 51 to which is lixedly attached a series of outwardly extended shoulders 32 pesitioned near one end of the shell 31. tending acro the shell 31 and removable therefrom is a fiber-holding tray l7 having a toraminous plate The pipe g t, attached to the shell 31 to coincide with an opening therein, and carries tie coupling 36 and the valve The pipe opens into the top of a liquid reserve tank 38. A smaller apparatus 39, the interior arrangement of parts of which is similar to the interior arrangement of parts of the receptacle is connected to the interior of the receptacle ;3 by means of the conduits l0 it) within the shell 31 carrying respectively the valves ll, 4:1, the interior of the apparatus 39 being connected to the top of the reserve tank by means of the pipe 101. The t e ting device 39 is connected to the valves l1, ll by means of couplings to allow the testing device to be removed from engagemcnt therewith. A thermometer $2 is introduced into the pipe 3i. Perforated steam pipes 935, are within the receptacle A pipe 83, carrying the valve ti l: opens into the interior of the receptacle for drawing the liquid from said receptacle. he interior of the receptacle, 23 carries a series of movable fiber-holding it Each trays l-l of the fiber-holding trays ll, lo and 4:6 is comprised of ator-ammous bottom to which are fixedly attached a series of lo l9, l9 and a side member 50 integral witn the for-aminous plate extends upwardly to the top of the lugs l9, i, said side member 50 being integral with and fixedly attached to the interior faces of the lugs l9 l9. The lugs l9, l9 areyertically movable within the lug-chambers 51 51 oi the shell 31. The interior of each of the fiberholding trays ll, l5 and 1-6 is therefore formed by the foramiuous bottom and the side member 50. The lugs l9. $9 of all of the fiber-holding trays carry holes with inserted pins 100 100 3501' ll e insertion of withdrawal means as hereinafter described,

Each of the two end tor-aminous bottoms 33, is composed of a series of parallel semi-circular adjacent bars 53, each bar carrying a series of upwardly extended pointed members 5st, with openings 55.

55 between said series of pointed members in order to allow the passage of liquid theretln'ougl1.

Each of the intermediate toraminous bottoms is composed of a series of spaced cylin drical bars 56 carrying series of upwardly and downwardly extended pointed members 5T, 5?, liquid being tree to pass through the openings 58, 58 between the bars 56 56.

An annular member 67 is extended into members (38, GS capable of abutment upon the lugs all), 4C9 ot' the end fiber-holding tray l6. The member 67 can be movably attached to the arms 32, ot the shell 31 by the screw-bolts 69, G9.

The fiberhol.ding member 103 is formed the same as the fiber-holding members l-h L5, ltl, 47 except that it has no side 'menr ber 50.

At the two ends of the receptacle are the hollow members til, 64: extended into the hollow members 65, 65 The arger end of each of the members (El, (llis of the same size and shape as the end of the re ceptacle 23 upon which it iscapable of abutment, and carries the angular collars 66, 66 capable of engagement with the annular member 70 of the receptacle 28, and the flange 95 of the shell 31 thus allowing tight engagement between the members (3t 64' and the receptacle The method of attaching the members G l, 64E to the shell 31 of the receptacle is as follows as shown in Figs. 2 and 8: A compressible gasket 82, 82 is inserted between the pyramidal shaped flange members 66 and 95, the gasket. being preferably formed of a number of pieces. The clamping member 59 is closed upon its hinge 60, the inclined inner faces of the clamping member abutting upon the inclined outer faces of the flange members 66 and 95, and the joint between the two flange members made tight by the pressure carried by means of the thumb-screw 61. The dotted lines of Fig. 8 showthe clamping member 59 in its open position, the oint between the flange members 66 and 70 being made is a similar manner. The centrifugal pumps 71, 71 are connected at their discharge ends with the members 65 by means of the pipes 90, 90 The charging ends of the pumps 71, 71 are connected with three-way pipes 73, 73 which three-way pipes are connected with the pipes H, M carrying the valves '75, 75% the pipes 76, 70* carrying the valves 77. 77 and the pipes 78, 78 carrying the valves 7 9 79 The pipes 74, H lead to a source of water supply, the pipes 76, 76 lead to the bottom of the liquid reserve tank 38, which is situated abo e the pumps 71. 71 and the pipes 78, 78 lead to a tank con taining the liquid in which the dye is dissolved. Connected with the pumps 71, 71

respectively are the two-way pipes 85, 85 branching into the pipes 86, 86 carrying the valves 87, 87 and opening into the air, and the pipes 88. 88* carrying the valves 89, 89-, connected with an exhaust and compression pump not shown. The pumps 71, 71 are connected with the pipes 90, 90 carrying the valves 91, 91 the pipes 90, 90 being connected to the top of the reservoir tank 38 by the pipes 92, 92 carrying the valves 93, 93

Situated within each of the members 6%, (E L is a nested series of conical members comprised of the annular members 80, 80, supported by the supporting members 81, 81, the length of each conical member being somewhat greater than that of the conical member directly within it, as shown 1n: Fig. 4s.

The operation of the device is as follows, assuming that the dyeing or treating operation has been finished, and the de ice in the position shown in Figs. 1 and 2: All the valves are closed with the exception of valve 8% thus allowing all the liquid contained within the receptacle to drain'out. The pipe is then uncoupled. The series of screw-bolts 61, 61, 61 61, are withdrawn, the clamping members 59, opened and the gaskets S2, S2 removed, thus freeing the receptacle "from engagement with the members 6e, 6-1. Truck 20 is then withdrawn from its position between the trucks 56, 56 by rolling it upon the tracks 22, 22. The receptacle is then given a quarter revolution by turning the wheel 29, and if necessary may be maintained in that position by the screw-bolt 9 1, the'receptacle 23 then being in the position shown in Fig. 3. The series of screw-limits 69, 69 (Figs. 1 and 2) are then withd 'awn from engagement with the lugs 32 and the member '67 withdrawn from within the receptacle The fiber-holding members i6, 4-5. the meniiber 103 and the fiber-holding members i4 and 4:7 are then ren'ioved in the order stated by means of hooks inserted beneath the pins 100. 100. in the lugs i l-9, 29, as illustrated in l? 3. lVheu it is desired to load the de vice with fiber. the fiber-holding member 17 (Fi 1) is introduced into the receptacle the device being in the position shown in Fig. 3 and fiber introduced therein, or the fiber may be introduced into the member i? before introduction into the receptacle. The fiberholding member l1- with the fiber is then similarly placed upon the member $7. The member 103 is then introduced. no fiber being contained therein, and finally the fiberholding n'iei-nbers and i6 with fiber are introduced. The member (37 is then introduced, its lugs 68. 6S abutting upon the lugs 49, 4:9 ot' the member 46, and the series of fiber-holding members brought into intimate and fixed contact with each other-by means of the screw-bolts 69, 69. The receptacle 23 and its contents are then given a quarter revolution by means of the wheel 29 and its connecting members. The truck 20 with the receptacle 23 is then moved along the tracks 22, until the receptacle is positioned between the members (Si, 6% aszshown in l i 1 and 2, and the joints between the recepta cle' and the members 6 1, 6% made tight as described above. The pipe 35 is fixedly attached to the shell 31. The device then in the position shown in Figs. 1 and The dyeing operation is then conducted as follows: Valve 84: is closed and valves 79*, 91 and 93 are opened. The pump 71 is then started, which takes the dye liquor from the dissolving tank, not shown, to which pipe 73* is attached, through the pipe 78 and forces it through the various fiber-holding trays %7, aid, 83, i5 and a6 into the pipe 92 through which it flows into the reserve tank 38. Then all of the liquor from the dissolving tank has been delivered to the pump 71*, the valve 79* is closed and the valve 77 is opened, thus allowing a free circulation of liquor by means of the pump 71*, from the tank 38, through the device and the fiber contained therein back into the tank 38.. If it is desired to reverse the flow of the dye liquor through the device and the fiber, the pump 71 is stopped, valves 77 and 93 are closed and valves 77, 91 and 93 are opened and pump 71 started, thus allowing a circula tion of the liquor in tank 38, through the pipe 7 6, the pump 71, the devices and through the pipe 93 back into the tank 38. If it is desired to pass the liquid from both ends of the device toward the middle and out through the space formed by the 111G111" her 103, all of the valves are closed with the exception of 77, 91, 7 7 91 and 37 and both pumps 71 and 71 started, the liquor will thus circulate from the tank 38, through both pump 71 and 71 inwardly through the fiber and back into the tank 38 through the pipe l hen the dyeing operation is completed the liquor in the dyeing chamber is removed by allowing it to drain through the pipe 83 by closing all the valves with the exception of valve 84: which is opened.

If it is desired to wash the goods, valve 8% is closed, water is admitted through the pipes 7%. 746* by opening the valves and 75 and the water forced through the device and the goods contained therein, the other valves being in such an open or closed position as to cause the water to enter either through the pipe 7% or 74* and exit through the other one, the circulation being caused by either the pump 71 or 71.

If it is desired to treat the dyed fiber with air, the valves 87 and 89 are opened and the exhaust pump (not shown) started, the other valves being arranged to allow air to be sucked in through the pipe 86, the device and fiber, by the suction upon the pipe 88 or by using the compression side of the pump (not shown) air may be forced through the device and the fiber in an opposite direction from that just described.

During all of these operations the valves 41 and tl are maintained in an open condition, thus allowing the fiber in the smaller device 39 to receive exactly the same treatment as that in the larger device, and the condition of the fiber in the larger device may be determined at any time without interrupting the process by closing the valves ll, H and examining the fiber in the smaller device 39.

One of the chief improvements in my device is the method whereby the dyeing chamber and its contents may be removed from the source of liquid supply without the neces sity of handling, or moving the latter, thus effecting a very considerable saving in time of operation and cost of erection.

I do not limit myself to the particular size, shape, number or arrangement of parts as described and illustrated, all of which may be varied without going beyond the scope of my invention as described and claimed.
